T 0 all whom it may concern.

Be it known that we, EDWARD F. NEED- HAM and THOMAS H. NEEDHAM, citizens of the United States, residing at Houston, in the county of Harris and State of Texas,

have invented certain new and useful Im-.

provements in Wall Construction, of which the following is a specification.

This invention relates to new and useful improvements in a wall construction.

One object of the invention is to provide a wall construction formed of slabs of concretious material so spaced and anchored together as to form a wall which when completed will be substantially hollow to permit the free circulation of air therethrough, and which is light and will require a minimum amount of material and which at the same time is of sufiicient strength to sustain the strains to which it may be subjected.

Another object of the invention is to provide a wall construction of the type specified which is formed of slabs of concretious material suitably spaced and anchored together, and veneering of brick or other individual units which is tied to the erected slabs thus forming a complete wall which is substantially hollow for the purpose above specified.

A further feature of the invention resides in the provision of a wall which is of comparatively simple construction and which may consequently be cheaply and easily erected.

With the above and other objects in view the invention has particular relation to cer tain novel features of construction, arrangement of parts and use, an example of which is given in this specification and illustrated in the accompanying drawings, wherein Figure 1 is a perspective view of a portion of the wall, shown partially in section.

Figure 2 is a perspective view of a portion of the wall as viewed from above, and

Figure 3 is a transverse sectional view of a portion of the wall, in perspective.

Referring now more particularly to the drawings, wherein like numerals of reference designate similar parts in each of the figures, the numeral 1 designates the base plate which is preferably formed of con crete. The upper side of this plate has a dove tailed groove 2 therein to receive the lower ends of the wall slabs 3, as well as the bottom course of the brick veneering 4.

The wall slabs are set along the inner side of said groove, their inner faces being flush forming the inside of the wall. Cast inte grally with the margins of the slabs are the outwardl extending ribs 5, 5 which fit together when the slabs are erected into the wall structure. These ribs extend from the lower end of the slab to near the upper end thereof and are then curved inwardly to ward each other and extend on to the upper end of the slab, and when said slabs are fitted together in a wall construction the inwardly turned upper ends of the ribs of adjacent-slabs form the dove tailed recesses 6,

which are closed at the bottom. Connecting said inwardly turned ends are the webs '7 which are spaced slightly below the upper ends of the slabs. A cap late 8 is poured while in plastic state on tl ie upper ends of the slabs, and key into the recesses 6, as well as into the spaces above said webs and when this plate hardens it is securel anchored to said slabs and also anchors t em together. Suitable reinforcing rods 9 are embedded within the slabs while they are plastic and extend above said slabs, and the cap plate 8 is poured around the upper ends thereof and these rods further anchor said plate upon the wall. After the slabs have been erected in position the veneering 4:, of brick or other individual units are then erected in place forming the outside of the completed wall. This veneerin is tied to the slabs and to the cap plate y means of suitable metallic straps 10 which are embedded in the ribs 5,- of the slabs, and in the cap plate, while they are in plastic state, with their outer ends projecting out, as illustrated in Figure 1 so that-the veneering may be tied to them.

Coinciding portions 11 of the ribs 5 are cut away, preferably as shown in Figure 1, to form spaces or openings for the circulation of air throughout the wall.

What we claim is 1. A wall slab formed with marginal ribs extending at approximately right angles to the body of the slab and whose upper ends are turned inwardly toward each other and a transverse web connecting the inturned ends of said ribs and spaced a short distance from the upper end of the slab.

2. A wall construction including adjacent wall slabs, the edges of said slabs being formed with ribs which extend at approximately right angles to theface of the slabs, the ribs of the adjacent edges of adjoining Q aaepve slabs fitting together and the upper ends of said adjacent ribs being spaced apart to form a recess between them, a transverse web connecting the upper ends of the edge ribs of the respective slabs, and an outer veneering for the wall.

3. A wall construction including wall slabs, the edges of said slabs beingformed with ribs which extend at approximately right angles to the face of the slab, the ribs of the adjacent edges of the adjoining slabs fitting together, said'ribs having cut away portions to form air passages, webs connecting. the upper ends of the ribs of the respective slabs, and an outer veneering for the Wall.

4. A wall construction including wall slabs having marginal ribs which extend 0utwardly at approximately right angles to the face of the slab, the ribs of the adjacent margins of the adjoining slabs fitting together, a cap plate molded onto the upper edge of the wall, means for anchoring the same in position, and veneering formed of individual units forming the outer side of the wall.

5. A wall construction including wall slabs, the edges of said slabs being formed with ribs which extend at approximately right angles to the face of the slab, the ribs of the adjacent edges of the adjoining slabs fitting together, said ribs having cut away portions to form air passages, webs connecting the upper ends of the ribs of the respective slabs, a cap plate molded onto the upper edge of the wall, means for anchoring the same in position thereon, a veneering formed of individual units forming the outer side of the wall.

6. A wall construction including wall slabs, the edges of said slabs being formed with ribs which extend at approximately right angles to the face of the slab, the ribs of the adjacent edges of the adjoining slabs fitting together, said ribs having cut away portions to form air passages, Webs connecting the upper ends of the ribs of the respective slabs, a cap plate molded onto the upper ends of the wall, means for anchoring the same in. position thereon, a veneering formed of individual units forming the outer side of the wall, and ties embedded within the cap plate and slabs while in plastic state, and anchored to said veneering.

7. Awall construction includingwall slabs having marginal ribs which extend outwardly at approximately right angles to the face of the slab, the ribs of the adjacent margins of the adjoining slabs fitting together, the upper ends of the adjacent ribs being spaced apart forming recesses whose bottoms are closed, a cap plate molded onto the upper edge of the wall and into said recesses, a veneering formed of individual units forming the outer side of said wall and means for anchoring the veneering and said slabs together.

8. Awall construction including wall slabs having marginal ribs which extend at approximately right angles to the face of the slab, the ribs of the adjacent margins of the adjoining slabs fitting together, a cap plate moulded onto the upper edge of the wall, means for anchoring the same in position, veneering formed of individual units forming the outer side of the wall, and ties secursaid veneering in position relative to the s a s.

In testimony whereof we have signed our names to this specification in the presence of two subscrlbmg wltnesses.
